Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically a cleaning robot. Background Technology

[0002] Cleaning robots are smart home appliances that integrate AI and mechanical technology, and can autonomously complete tasks such as sweeping and mopping the floor. Their core technologies include LiDAR or visual navigation, 22000Pa super suction power, AI obstacle avoidance and self-cleaning base station.

[0003] Traditional cleaning robots typically use a cleaning brush in conjunction with vacuuming to perform cleaning.

In summary, by setting a detachable dust collection box 12, it is convenient to collect and process dust, and the air pump can be exposed when the dust collection box 12 is removed, which facilitates the maintenance and replacement of the air pump.

[0020] Working Principle: When cleaning the floor, this device moves and turns using wheels and guide wheels at the bottom of the outer casing 1. During cleaning, the rotating cleaning roller 3 continuously sweeps the floor. When the air pump is turned on, its suction end works with the dust collection box 12 and dust hopper 4 to create suction force, drawing dust into the dust collection hopper 4. Dust on the floor is collected as the device passes through the dust collection hopper 4. Small dust particles enter the dust collection box 12 through the through-groove 7 and the gap at the top of the front half of the partition 5, while larger dust particles are collected separately. When dust comes into contact with the curved surface of the front wall of the classifying plate 6, it is guided to both sides and finally accumulates in the gap between the outer side of the partition plate 5 and the inner side of the dust collection hopper 4. Small dust particles, after entering the dust collection box 12, are filtered by the filter cloth inside the dust collection box 12. The filtered airflow then enters the suction pump and is discharged through the two pipes 10. Finally, it is blown towards the front of the dust collection hopper 4 through the opening of the blowing box 8. At this time, the airflow discharged by the blowing box 8 is an oblique airflow towards the dust collection hopper 4, which will blow the dust that is about to enter the dust collection hopper 4 into the dust collection hopper 4.
